Games considered to be "competition" include World of Tanks, World of Warcraft, Hearthstone, Dota 2, and StarCraft. An official response from the company states that this is comparable to the restrictions placed on pro athletes in several sports.

It remains to be seen whether or not this will impact the game's championship numbers in any fashion.
